Bets are positioned either before receiving the cards or after receiving and viewing the primary card. The punters, in turn, having picked up and examined both playing cards announce whether or not they will stay with the cards they’ve or receive another card from the banker free. Some games additionally permit a punter to raise his stake and ‘buy’ another card. The aim is to attain precisely twenty-one factors or, failing that, to come back as close to twenty-one as attainable, based mostly on the card values dealt. If a player exceeds twenty-one, they lose their stake.
